INVENT OR. ROBERT W. ANKNEY ATTORNEY United States Patent 3,115,284DISPENSING SPOUT FOR METALLIC CONTAINERS Robert W. Ankney, Redford, OhioThe Ankney C0., 8007 Grand Ave., Cleveland 4, Ohio) Filed July 15, 1957,Ser. No. 671,846 11 Claims. (Cl. 222566) This invention pertains to theart of fastening plastic articles to metal and more particularly tofastening a plastic sleeve in an opening in sheet metal in such mannerthat a sealed joint is obtained there-between.

This application is a continuation-in-part of my copending applicationSerial No. 640,757, filed February 18, 1957, now abandoned.

The invention is particularly applicable to the fastening of dispensingspouts in sheet metal containers, particularly when containingdetergents or other corrosive liquids or the like, and will be describedwith particular reference thereto, although it will be appreciated thatthe invention has broader applications and may be used generallywhenever a plastic sleeve must be securely fastened in an opening insheet metal.

In the art of manufacturing containers for detergents, it has heretoforebeen conventional to assemble the pouring spout with an end of thecontainer and then assemble the end with the other parts of thecontainer. This was necessary since the spout in heretofore designs hadto be inserted in the opening in the end of the container from the sidethereof which would be on the inside of the completed container. Theprotruding pouring spout on the container end made the end difiicult tohandle in a very high production assembly line operation. Further, itrequired filling the container through the pouring spout, thus makingthe filling operation not only more difficult because of the problem ofaligning the filling nozzle with the opening in the pouring spout, butalso more time consuming because the rate of fill due to the restrictedarea of the dispensing spout opening was considerably reduced. In asingle filling machine where 500,000 cans might be filled in one day,split fractions of a second can make a substantial difference in theoverall production.

The present invention contemplates a filling spout which may beassembled with a container after the container has been filled.

Another problem with metallic containers with plastic spouts andcorrosive materials such as detergents has been the corrosion of themetal container adjacent the edge of the opening in which the spout isinserted. Ordinarily the metal containers have a corrosion resistantcoating on the inside. However, the opening for the dispensing spout isordinarily formed after the metal is coated with a corrosion resistantprotective coating. The forming of this opening ruptures the protectivecoating and exposes the metal around the opening to corrosive action.Heretofore, to protect the edges of the opening, various means have beenprovided to hold the base of the spout in sealing engagement with theinner surface of the container. Some of these have been successful to agreater or lesser degree but have always necessitated that thedispensing spout be inserted into the container opening from the sidewhich will be on the inside of the completed container.

The present invention contemplates a pouring spout which can be insertedin the container opening from the outside and which will protect anyruptures which might exist in the protective coating surrounding theopening from the corrosive action of the container contents.

A still further difliculty which in some respects was emphasized by theabove referred to patent application was the maintenance of sufficientlyhigh pressures be- 3,115,284 Patented Dec. 24, 1963 tween the plasticspout and the metal container so that a high torque was required to turnthe spout relative to the container. The plastics normally employed forpouring spouts have a tendency to cold flow under pressure with theresult that the torque required to turn the spout relative to thecontainer became progressively less. If the container was heated at allto elevated temperatures, the problem became particularly severe.

The present invention contemplates a pouring spout arrangement whichmaintains a uniformly high turning torque over a long period of time.

In accordance with the present invention, the container end or side hasan opening into which the pouring spout is to be inserted which isdefined by an out-turned flange. The pouring spout is comprised of asleeve of pliable material having a portion with outer dimensions so asto fit snugly within the out-turned flange and having an inwardly facingshoulder to position the portion longitudinally within the flange oropening. The pouring spout has a longitudinally extending passagerestricted slightly by a shoulder generally close to or aligned with theplane of the inner surface of the container. A rigid ferrule havingouter dimensions generally equal to the inner dimensions of the pouringspout passage is then inserted longitudinally therein and towards theinterior of the can until it moves past the shoulder. As the ferrulemoves past the shoulder, the pouring spout is forced outwardly so as toform a rigidly held bead of larger dimension than the container openingwhich bead bears against the inner surface of the container around theopening and retains the pouring spout in position with a sealed jointtherebetween. The friction between the outer surface of the ferrule andthe inner surface of the pouring spout retains the ferrule in assembledposition.

Further in accordance with the invention, the container opening isprovided with at least two major dimensions and may thus be in the shapeof an ellipse or polygonal shaped figure such as a triangle, rectangleor the like with the corners of such polygonal shaped figure beingarcuate. The portion of the spout which fits into the container openinghas a like shape.

Preferably, although not necessarily, the spout passage at leastopposite the portion which will fit within the container flange and therigid ferrule also has a simi lar shape. Further preferably, the largerdimension of the ferrule is greater than the minimum dimension of thecontainer opening.

Further in accordance with the invention, the inner end of the portionwithin the out-turned flange has an outwardly facing sharp corner whichwhen the passage shoulder is forced outwardly, is forced into pressuresealing engagement with the inner surface of the container end.

The principal object of the invention is the provision of a new andimproved arrangement for fastening a pliant sleeve in an opening insheet metal which is simple in construction, economical to manufacture,is readily assembled and maintains its resistance against turning overlong periods of time.

Another object of the invention is the provision of a new and improvedplastic pouring spout which may be assembled With a container after thecontainer has been filled.

Another object of the invention is the new and improved dispensing spoutfor containers which provides an eifective seal around the edges of theopening in the container so as to prevent corrosive fluids in thecontainer from coming into contact with the edges of the pouring spoutopening.

Another object of the invention is the provision of a new and improvedpouring spout arrangement for metal lic containers wherein as the innerend of the pouring spout is forced outwardly to prevent removal of thepouring spout, a sharp corner on the pouring spout comes into sealingengagement with the inner surface of the container spaced from the edgesof the pouring spout opening.

The invention may take physical form in certain parts and arrangementsof parts, the preferred embodiment of which will be described in detailin this specification and illustrated in the accompanying drawings whichform a part hereof and wherein:

FIGURE 1 is a side cross-sectional view of the cover of a container witha dispensing spout assembled therewith and illustrating an embodiment ofthe invention;

FIGURE 2 is a fragmentary view of FIGURE 1, but showing the parts inexploded view before assembly; and,

FIGURE 3 is a view similar to FIGURE 2, but showing an alternativeembodiment of the invention;

FIGURE 4 is a view similar to FIGURE 1, but illustrating the preferredembodiment of the invention;

FIGURE 5 is a fragmentary exploded view of FIGURE 1 showing the partsbefore assembly; and,

FIGURE 6 is a cross-sectional view of FIGURE 4 taken approximately onthe line 66 thereof.

Referring now to the drawings wherein the showings are for the purposesof illustrating a preferred embodiment of the invention only and not forthe purposes of limiting same, the figures show a container wall or end11) having an opening 11 defined by an out-turned flange 12 in which apouring spout 13 is positioned and held in place by a ferrule 14. A cap15, which forms no part of the present invention, is screwed over theouter end of the spout 13 to close the same.

The end may be formed of any desired material, but normally is formed ofsheet steel having a coating on the inner surface thereof so as toprotect the steel from the corrosive action of materials, not shown, tobe dispensed from the container. The out-turned flange 12 is formed in aconventional manner such as by stamping and drawing presses. It will benoted that the flange 12 joins the end 10 at a relatively sharp corner21 and the formation of this sharp corner sometimes tends to rupture thecoating 20 at the apex 22 of the bend. It is at this point of rupturethat the materials on the inside of the container can contact the metalof the end 10 and cause the same to rust or corrode unless this point ofrupture is protected in accordance with the present in vention.

The pouring spout 13 has an outer end or portion of any desired form orshape which extends beyond the free outer or upper end 12a of the flange12, and has an inner or lower portion 24 having an outer diametergenerally equal to the inner diameter of the flange 12 and this opening11. When the spout 13 is inserted in the opening, the outer surface ofthe portion 24 will fit snugly against the inner surface of the flange12. The spout 13 has a shoulder 25 bearing against the free or upper end12a of the flange 12 to axially locate the spout 13 therein and in theopening 11. The lowermost part of the portion 24 is chamfered as at 26so as to facilitate the insertion of the portion 24 in the opening 11.The outer surface of the portion 24 is provided with a circumferentiallyextending groove 27 located a distance from the shoulder 25 and betweenthe shoulder 25 and the chamber 26 so as to be located generally in theplane of the inner or lower surface of the end 10 when the spout 13 isassembled with the end 10. The groove 27 provides a dual function,namely of providing a thin web portion 36, thus making the lower end ofthe portion 24 flexible or pivotal relative to the upper portions of theportion 24, and additionally the surface of the groove 27 intersectswith the outer surface 24 so as to form a sharp corner 29 for reasonswhich will appear hereinafter.

With the arrangement as described, when the spout 13 is assembled in theopening 11, the shoulder 25 bears against the upper edge 12. The groove27 is located generally in the plane of the inner surface of the end 10.

4 The outer surface of the portion 24 bears with a slight pressureagainst the inner surface of the flange 10, but not with suflicientpressure to hold the pouring spout in position, nor to provide thesealing action desired.

It is to be noted that the pouring spout 13 is preferably of a pliantmaterial and in preferred embodiments of the invention is made from amolded polyethylene plastic material. This material, as it is known, hasa capability of substantially deforming under pressure and a capabilityso as to return from the deformation to its original shape when thepressure is removed.

The pouring spout 13 has a passage therethrough slightly restricted atits lower end by an inwardly and downwardly tapered shoulder 30 which isengaged and moved outwardly by the ferrule 14 as the ferrule isinserted. This causes the lower or inner end of the spout 13 to bedeflected radially outwardly to bring the corner 29 into sealingengagement with the inner surface of the end 11) at a location radiallyoutwardly from the apex 22 and opening 11.

The ferrule 14 is generally in the form of a cylinder of relativelyrigid material and has an outer diameter generally equal to the innerdiameter of the spout 13. The ferrule 14 has a downwardly and inwardlybeveled lower corner 32 as indicated. Normally the upper corner of theferrule 14 will likewise be beveled as at 33 so that the ferrule may beassembled with the pouring spout 13 and without regards to which end isinserted first into the spout.

After the pouring spout 13 is positioned in the flange 12 and thus theopening 11, the ferrule 14 is then forced axially inwardly to theposition shown in FIGURE 1. As the ferrule 14 is forced inwardly, thebevel 32 contacts the annular shoulder 33 and forces it radiallyoutwardly. The lower end of the SPOIllt 13 pivots around the thin webportion 36 formed by the groove 27 so that the corner 29 moves intocontact with the inner surface of the container end 10.

In accordance with the invention, the corner 29 must engage the innersurface of the end 10 radially outwardly of the point 22 so as to coverany ruptures at this point 22 and in the coating 20. Corner 29 must besharp so that a high unit pressure results. This high unit pressureprevents the contents of the container from flowing there past so as tocome into contact with the sheet steel of the end 10 through anypossible rupture in the coating or film 20 at the point 22.

The angle of the bevel 32 and the angle of the shoulder 30 as well asits radial thickness from the inner surface of the spout 13 are alladjusted in relation to the ability of the container end 10 to withstandan axial force with out collapsing or bending. As the angle A of thebevel 32 is increased, obviously this pressure will increase. The angleA, in accordance with the preferred embodiment, may have a value ofbetween 30 to 45.

In a like manner, .the angle B of the shoulder 30 may be as :desired,and as this angle increases, less and less axial force is required. Itis preferred, however, that the bevel 32 contact the shoulder 30 at apoint close to its minimum diameter. In order to assure this, the angleB should always be greater than the angle A. Preferably the angle A is30 and the angle B is 45, although obviously these angles may be variedfrom those stated. With such angles, generally the maximum deformationmay be obtained using a minimum axial force on the ferrule. The axialforce may then be adjusted by adjusting the radial thickened portionformed by the shoulder 30. The radial thickness of this portion to someextent determines the radial outward movement of the shoulder 29. It isdesirable that this shoulder move outwardly as far as possible to assurethat any rupture in the coating 20 shall be completely sealed from thecontents of the container by the sealing engagement of the corner 29with the inner surface of the container end 10.

FIGURE 3 shows an alternative embodiment of the invention which assistsin having the corner 29 engage the inner surface of the end 10 at themaximum radial distance from the center-line of the opening 11. in FIG-URE 3, the spout 13' has a portion 40 below the groove 27' of an outerdiameter slightly greater than the diameter of the portion 24' above thegroove 27 and a diameter slightly greater than the diameter of theopening 11. With the arrangements shown in FIGURES l and 2, the spout 13may be inserted in the opening 11 with substantially no axial force.With the arrangement shown in FIGURE 3, the spout 13' must have anappreciable axial force exerted thereon so as to force the spout intothe opening 11. This force is less than the force required to collapsethe end. However, once the spout 13 is inserted into the opening 11, itwill be noted that the corner 29 is radially outward from the innersurface of the flange 12. Thus, the radial thickness of the portionformed by the shoulder 30' may be less than that shown in the FIGURE 2in order to have the :corner 29 engage at the same point on the innersurface of the end 10. With this reduced radial thickness, less axialpressure will be required to force the ferrule 14 into position. As theforce to push the spout 13 into the opening 11 and the force to push theferrule 14 into the spout 13 are both exerted at different times, itwill be seen that the arrangement of FIGURE 3 permits the same sealingaction of FIGURES 1 and 2 to be obtained with the same total force, butwith a lesser maximum force. Alternately, a greater sealing action canbe obtained with a greater total force, but the same maximum axialforce.

The above described embodiments have proven quite satisfactory inpractice with a single exception. Thus it was found that the portion 24which was under pressure between the flange 12 and the ferrule 14 tendedto cold flow so as to reduce this pressure with the result that thefrictional force between the portion 24 and the flange 12 wassubstantially reduced. Thus after a period of time the torque requiredto turn the spout relative to the top then was substantially reduced.The effect became quite pronounced when the tops were heated to elevatedtemperatures for even short periods of time.

The embodiments of the invention shown in FIGURES 4, 5 and 6 incorporategenerally the principles of the embodiments shown in FIGURES 13, but inaddition, have the feature that they have a uniformly high resistanceagainst turning and the effects of 'cold flow plastic will not adverselyaffect such characteristics.

Thus in the embodiment of the invention shown in FIGURES 4 and 5, thecontainer end 110 has an opening 111 which is generally rectangular inshape and is defined by an upwardly or outwardly turned flange 112 whichflange may be said to have generally parallel sides and arcuate corners.The portion 124 of the spout 113 which fits within the opening 111defined by the flange 112, has an external shape identical to the shapeof the opening 111. Thus when the spout 113 is positioned within theopening 111, the outer surfaces of the portion 124 will generally be infirm engagement with the inner surfaces of the flange 112. I

Immediately below the lower end of the portion 124, the spout 113 has anoutwardly extending portion 140 having a sharp corner 141, the plane ofthis corner being in the lower plane of the top 110. The inner surfaceof the spout 113 has a similar rectangular shape to that of the opening111 and is restricted at its lower end by means of a shoulder 130, theupper plane of which is generally in the plane of the inner surface ofthe top 110. The ferrule 114 likewise has a rectangular shape witharcuate corners and when inserted in the spout 113 engages the shoulder130 to force it sidewardly and force the point 141 into sealingengagement with the inner surface of the top 110 sidewardly of thecorner 112.

It will be appreciated that with the shape of the opening 111 shown andthe rigid ferrule 114 of a similar shape, greatly increased torques willbe required to turn the spout relative to the container. In thisrespect, it is preferred that the outer diagonal of the ferrule 114 begreater than the minimum transverse dimension of the opening 111.

It will (also be appreciated that other shapes of openings 111 could beemployed, the important thing being that the opening have a major and aminor dimension. Such other shapes meeting these requirements would beellipses or other polygonal shapes. In all instances of polygonal shapesit is preferred that the sides be joined by arcuate corners.

It should also be appreciated that in some instances it is possible thatthe inner surface of the spout be generally circular and that theferrule also be circular, the difference in the spacings between thewalls of the ferrule and of the flange 112 being taken up by a variationin the dimensions of the portion 124. It is preferred, however, that theportion 124 have a uniform thickness around the entire periphery.

It is also to be noted that in this embodiment of the invention, thegroove 27 is not employed. There is thus a maximum amount of materialbetween the ferrule 114 and the plane of the top 110. It is to befurther noted that any torque on the spout is transmitted to the top inthe plane of the top which, as will be obvious, is the strongest portionthereof.

Referring now to FIGURE 4, at the upper end of the spout 113 and on theinner surface, a small shoulder 142 is provided Which serves thefunction of preventing the ferrule 114 from shaking out of the spout 113during shipment and before assembly of the spout 113 with a container.Following such assembly, the frictional engagement between the ferrule114 and the spout 113 is sufficient to retain the ferrule in place.

In this embodiment of the invention, the ferrule 114 preferably extendsupwardly so as to provide a backing behind the threads 144.

It is to be noted that the present invention embodies the principles ofmy co-pending patent application Serial No. 618,955, filed October 29,1956.

The present invention differs from the invention of that application inthe use of the groove 27 and the shoulder 30. The advantages of theferrule 14 as described in that application are likewise present herein;namely, of a stronger fit into the opening 11 as well as the radial support for the threads used to fasten the cap 15 onto the pouring spout13. These advantages become particularly apparent when it is realizedthat a round thread may be employed as distinguished from a squarethread. Round threads, as illustrated in the present drawings, may bestripped from a solid mold whereas when square threads are employed, asplit mold must be used.

It will thus be seen that embodiments of the invention have beendescribed which accomplish all the objects heretofore set forth andothers, and that arrangements for fastening a dispensing spout to acontainer have been provided which are simple in construction, areeasily assembled with a can after the can itself has been assembled andfilled, and which provide a highly effective sealmg action.

Obviously, modifications and alterations will occur to others uponreading and understanding of the above description. It is my intentionto include all such modifications and alterations insofar as they comewithin the scope of the present invention.
